How quickly can the X1 restart a dead car battery?

What can the built-in air compressor do for me?

The integrated 150 PSI turbo pump inflates car tires, SUVs, bikes and sports balls fast and stops automatically when the preset pressure is reached. A high flow rate and multiple nozzle options make it suitable for roadside inflation, camping and recreational gear.

• Green/red LED connection indicators for correct hookup
• Protections: anti-spark, reverse polarity, overheat, overload and low-voltage
• QDSP battery/component design to lower operating temperature during high current draws

How portable is the jump starter and what extras does it include?

The X1 is engineered to be lightweight and multi-use for travel and emergency kits while still offering practical extras for daily use. It charges phones via USB, features a multi-mode LED work light, and ships with all necessary inflation fittings and a smart clamp.
